Mauro Carvalho Chehab 5a5e045bb3 docs: isdn: convert to ReST and add to kAPI bookset
The ISDN documentation is a mix of admin guide, uAPI and kAPI.

Ideally, it should be split. Yet, not sure if it would worth
the troble. Anyway, we have the same kind of mix on several
drivers specific documentation. So, just like the others, keep
the directory at the root Documentation/ tree, just adding a
pointer to it at the kAPI section, as the documentation was
written with the Kernel developers in mind.

================================
Driver for active AVM Controller
================================
The driver provides a kernel capi2.0 Interface (kernelcapi) and
on top of this a User-Level-CAPI2.0-interface (capi)
and a driver to connect isdn4linux with CAPI2.0 (capidrv).
The lowlevel interface can be used to implement a CAPI2.0
also for passive cards since July 1999.
The author can be reached at calle@calle.in-berlin.de.
The command avmcapictrl is part of the isdn4k-utils.
t4-files can be found at ftp://ftp.avm.de/cardware/b1/linux/firmware
Currently supported cards:
- B1 ISA (all versions)
- B1 PCI
- T1/T1B (HEMA card)
- M1
- M2
- B1 PCMCIA
Installing
----------
You need at least /dev/capi20 to load the firmware.
::
mknod /dev/capi20 c 68 0
mknod /dev/capi20.00 c 68 1
mknod /dev/capi20.01 c 68 2
.
.
.
mknod /dev/capi20.19 c 68 20
Running
-------
To use the card you need the t4-files to download the firmware.
AVM GmbH provides several t4-files for the different D-channel
protocols (b1.t4 for Euro-ISDN). Install these file in /lib/isdn.
if you configure as modules load the modules this way::
insmod /lib/modules/current/misc/capiutil.o
insmod /lib/modules/current/misc/b1.o
insmod /lib/modules/current/misc/kernelcapi.o
insmod /lib/modules/current/misc/capidrv.o
insmod /lib/modules/current/misc/capi.o
if you have an B1-PCI card load the module b1pci.o::
insmod /lib/modules/current/misc/b1pci.o
and load the firmware with::
avmcapictrl load /lib/isdn/b1.t4 1
if you have an B1-ISA card load the module b1isa.o
and add the card by calling::
avmcapictrl add 0x150 15
and load the firmware by calling::
avmcapictrl load /lib/isdn/b1.t4 1
if you have an T1-ISA card load the module t1isa.o
and add the card by calling::
avmcapictrl add 0x450 15 T1 0
and load the firmware by calling::
avmcapictrl load /lib/isdn/t1.t4 1
if you have an PCMCIA card (B1/M1/M2) load the module b1pcmcia.o
before you insert the card.
Leased Lines with B1
--------------------
Init card and load firmware.
For an D64S use "FV: 1" as phone number
For an D64S2 use "FV: 1" and "FV: 2" for multilink
or "FV: 1,2" to use CAPI channel bundling.
